My 2023 Duramax with 84k is a giant pos, which is sad because I traded in my reliable 2016 Duramax with 200k on it to buy the turd.
I'm on my second transmission, second turbo, second emissions system, and had to drop it off at the dealer a few weeks ago because it got stuck in regen mode but wasn't regenerating so they had to force it multiple times because the dpf (which was new 10k miles ago) was too clogged up. They told me to stop idling so much….. Which is the point of owning a diesel….?
Even though it's my small business vehicle my wife is tired of it and is demanding we replace it when the warranty runs out.
I can't trust it to pull our camper so I bought a 2005 8.1 Suburban for that job.
Very disappointing. I'd stick with the Powerstroke.
